<h2><a name="project-layout">1. How can I force a Flat project layout in the <i>Project Explorer</i> view?</a></h2>
<p>As default Project Layout in Project Explorer has been switched to hierarchical, a new preference is available for RCP providers who want to force Flat layout by default instead. The preference is
<code>org.eclipse.ui.navigator.resources/defaultToFlatLayout</code> and can be set to <code>true</code> in <code>plugin_customization.ini</code> or programatically <i>before</i> Project Explorer opens
for the first time, in order to force a Flat project layout. Subsequent change to this preference after first initialization of Project Explorer will have no effect.</p>
